I have separated out the C71 platform driver pieces (patches 1 & 4) and
posted a v2 for those.
Appreciate any feedback on the core patches (patches 2 & 3) that add the
minimal 64-bit trace support, as this also sets the direction for
resource extensions. I can post the next version for those based on
feedback.
